Hello,
As you have noticed i have just provided you with PerlMaple package..
And more about Perl and Python..
I know how to program in Perl, and i think Perl is powerful and is
better than Python, and you can in Perl set a property or a method of a
class to be private or public by the following Perl methodoly, read my following program to notice it:
================================================
package class_A;
my $private_method = sub { #_{
#
# Declaring a private method. The method apparantly can not be called
# from outside this package.
#
my $self = shift;
$self->echo("private_method was called");
}; #_}
sub new { #_{
my $class = shift;
my $self = {};
bless $self, $class;
return $self;
} #_}
sub public_method {
my $self = shift;
$self->echo("public_method was called, going to call private method");
# Call private method.
$self->$private_method();
}
sub echo { #_{
my $self = shift;
my $text = shift;
print "$text\n";
} #_}
1;
------
#!/usr/bin/perl
use warnings;
use strict;
use class_A;
my $ca = class_A->new();
$ca->public_method();
=============================================================
And here is also why Python is not good: Python has a global interpreter
lock, but Perl threads can execute in parallel, read this:
What is the Python Global Interpreter Lock (GIL)?
https://realpython.com/python-gil/
And RPerl compiler for Perl is here..
I also use Perl, so here is an interesting new website about RPerl and Perl:
http://perlcommunity.org/#performance
And about Perl in 2020: Is It Still Worth Learning Now?
